The Power Class delivers crisp, bright, highly resolved images at any distance, maintaining image quality regardless of recoil, weather or shooting conditions. Their European style 30mm tubes offer added strength and rigidity, while providing up to 40 MOA adjustments for windage and elevation in either direction. And, with their extra large objective lens, the Power Class scopes present the widest field of view and let in the most light, a perfect combination for hunting in low light conditions. This is the last scope you'll ever need.
